Keyestudio MLX90614 Non-contact Infrared Temperature Sensor GY-906 for Arduino/IIC port

The Keyestudio MLX90614 Non-contact Infrared Temperature Sensor is a high-precision thermal measurement module designed for Arduino and other I2C-compatible microcontrollers. It is perfect for students, makers, and hobbyists looking to build contactless thermometers, environmental monitoring stations, or robotic safety systems.

Contactless thermal sensing

This module utilises the MLX90614 infrared thermometer to measure surface temperatures without making physical contact. It is ideal for hygienic temperature checks or monitoring hot, moving parts in robotics projects.

Integrated TO-39 package

The sensor features a robust TO-39 metal can package that houses both the MLX81101 infrared induction thermoelectric pile detector chip and the MLX90302 signal processing chip. This compact design ensures reliable performance and protection from environmental interference.

High-resolution analogue conversion

An onboard low-noise amplifier and a 17-bit analogue-to-digital converter process the weak thermopile signals with exceptional accuracy. This allows the sensor to resolve minute temperature differences for highly sensitive applications.

Onboard digital signal processing

A built-in digital signal processing unit handles the complex calculations required to output accurate temperature readings directly. This reduces the processing load on your host microcontroller, making your code simpler and more efficient.
